Physical Activity Together for Multiple Sclerosis (PAT-MS): A randomized controlled feasibility trial of a dyadic behaviour change intervention

Background

Many people with advanced multiple sclerosis (MS) and their care-partners do not engage in sufficient physical activity (PA) for health benefits. We developed "Physical Activity Together for MS (PAT-MS)", a 12-week dyadic behavioural intervention, to promote PA among these dyads. Herein, we evaluated the feasibility of PAT-MS before a definitive trial.

Methods

A randomized controlled feasibility trial, with 1:1 allocation into the intervention or wait-list control condition. Predefined progression criteria included rates of recruitment, retention, safety, participant satisfaction and adherence. Changes in self-reported and accelerometer-measured PA were assessed at baseline and post-intervention using mixed-factor ANOVAs. Effects sizes were calculated as Cohen's d.

Results

The recruitment rate (i.e., 20 participants in 10 months) was not acceptable. However, retention (80%) was acceptable. No serious adverse events were reported. There were high levels of participant satisfaction with the intervention (content (median = 6 out of 7), facilitator (median = 7 out of 7), and delivery (median = 5 out of 7)) and adherence (92% of the group sessions, 83% of the individual support calls, and 80% of the practice activities were completed). There were statistically significant time-by-condition interactions on self-reported PA, steps/day, and %wear time and minutes in sedentary behaviour, and moderate-to-vigorous PA from baseline to post-intervention in people with MS and their family care-partners.

Conclusion

PAT-MS appears feasible, safe, and efficacious for PA promotion in MS dyads. We established effect size estimates to power a future definitive trial and identified necessary methodological changes to increase the efficiency of study procedures and improve the quality of the intervention.

An innovative approach to recruiting participants for dementia research: primary care and researcher perspectives

Aim: To describe clinician and researcher perceptions of a new, patient preference focused approach to recruiting patients for research from primary care-based memory clinics. Methods: Memory clinic clinicians completed a survey and key informants completed an individual interview to gather their perceptions of this new program. Results: The majority of clinicians were 'satisfied' or 'very satisfied' with this recruitment approach and indicated that this approach would have minimal negative impact on patient care or create conflict of interest. Key informants valued the program for its patient-centred approach, the integration of research into care and potential for increased recruitment. Discussion: These findings are suggestive of support for this recruitment approach. Pilot testing will inform feasibility, effectiveness and process improvements.

Prerandomization withdrawals from a Type 2 diabetes self-care support intervention trial are associated with lack of available support person coparticipant

OBJECTIVES

Dyadic interventions, involving two persons with a preexisting close relationship, offer the opportunity to activate support persons (SPs) to improve health for adults with chronic conditions. Requiring SP coparticipation can challenge recruitment and bias samples; however, the associations between voluntary SP coparticipation and recruitment outcomes across patient characteristics are unknown.

METHODS

The Family/Friend Activation to Motivate Self-care 2.0 randomized controlled trial (RCT) enrolled adults with Type 2 diabetes (T2D) from an academic health system. Participants were asked-but not required-to invite an SP to coenroll. Using data from the electronic health record we sought to describe RCT enrollment in the setting of voluntary SP coparticipation.

RESULTS

In a diverse sample of adults with (T2D) (48% female, 44% minoritized race/ethnicity), most participants (91%) invited SPs and (89%) enrolled with SPs. However, prerandomization withdrawal was significantly higher among participants who did not have consenting SPs than those who did. Females were less likely to invite SPs than males and more Black PWD were prerandomization withdrawals than randomized.

DISCUSSION

Voluntary SP coenrollment may benefit recruitment for dyadic sampling; however, more research is needed to understand if these methods systematically bias sampling and to prevent these unintended biases.

Recruiting Persons with Dementia and Caregivers in a Clinical Trial: Dyads Perceptions

Recruitment for dementia research is challenging and costly. Using Ajzen's Theory of Planned Behavior we explored attitudes, perceived norms, and perceived behavioral control of persons living with dementia (PLWD) and their caregivers who participated in one clinical trial to better understand factors that influence dyads' decisions to enroll. We conducted semi-structured telephone interviews with 12 PLWD and 9 caregivers and utilized directed content analysis. Categories connected with positive attitudes about study enrollment were personal desires of wanting to learn and in-person meetings with knowledgeable staff. Additionally, participants said the money always helps in terms of the financial incentive. Participants reported enrolling to support another person (perceived norm). Study requirements were thought to be easy (perceived behavioral control). Participants highlighted the importance of flexible scheduling and study tasks being completed at their home. Findings can inform future recruitment efforts and should be investigated as effective recruitment methods in other clinical trials.

Recruitment of a diverse research cohort in a large metropolitan area for dementia intervention studies

The human and financial costs of dementia care are growing exponentially. Over five and a half million older Americans are estimated to be living with Alzheimer's disease and related dementia (ADRD). By 2050, this is expected to increase to over 13 million, and persons of color are at the highest risk. Considerable funds have been committed to research to prevent, treat, and care for persons at risk for ADRD. However, enrollment of research participants, particularly those coming from diverse backgrounds, is a perennial challenge and has serious implications. This paper quantitatively details the results of a community-based multi-modal outreach effort to recruit a racially diverse sample for non-pharmacological dementia intervention, including referral and participant sources and yield, total recruitment costs and cost per enrolled dyad, and a qualitative description of lessons learned, with particular attention to the recruitment of Black participants. The largest number of referrals and referrals converting to study participants, for both Black and White persons, were from a Maryland Department of Health mailing to Medicaid recipients. There was an important difference in the most effective strategies, proportionally, for white and Black participants. The MDH mailing had the highest yield for our Black referrals and participants, while professional referrals had the highest yield for white referrals and participants. The total estimated cost of recruitment was $101,058, or $156.19 per enrolled dyad. Ultimately 646 persons with dementia and care partner dyads were enrolled, 323 (50%) of whom were Black.

A national open-access research registry to improve recruitment to clinical studies

INTRODUCTION

Barriers to recruitment for dementia studies are well documented. As part of the UK government's Dementia 2020 strategy, a nationally consistent system to increase public engagement and participation in research was launched in February 2015.

METHODS

We describe the development of the "Join Dementia Research" registry, including evolution of policy, involvement of people with dementia in co-production, data requirements, governance, technology, and the impact on study recruitment and what factors may have contributed to the services success.

RESULTS

The UK-wide online, telephone, and postal service has registered 47,071 volunteers, with 33,139 people (67.9% of all volunteers) taking part in 378 studies, with 49,954 total study enrolments. This has taken place across 295 research sites, involved 1522 researchers, and resulted in 134 peer-reviewed publications.

DISCUSSION

Public registries of individuals interested in research, with user-provided data enabling basic phenotyping, are effective at increasing public engagement with research and removing barriers to study recruitment. Deeper pheno/genotyping could be undertaken to improve matching, but how and when that information is collected will be a key factor.

Recruitment of Community-Based Samples: Experiences and Recommendations for Optimizing Success

Background

Recruitment in health and social science research is a critically important but often overlooked step in conducting successful research. The challenges associated with recruitment pertain to multiple factors such as enrolling groups with vulnerabilities, obtaining geographic, cultural, and ethnic representation within study samples, supporting the participation of less accessible populations such as older adults, and developing networks to support recruitment.

Purpose

This paper presents the experiences of two early career researchers in recruiting community-based samples of older adults, their caregivers, and associated health providers.

Methods

Challenges and facilitators in recruiting two community-based qualitative research samples are identified and discussed in relation to the literature.

Results

Challenges included: identifying potential participants, engaging referral partners, implementing multi-methods, and achieving study sample diversity. Facilitators included: making connections in the community, building relationships, and drawing on existing networks.

Conclusions

Findings suggest the need for greater recognition of the importance of having clear frameworks and strategies to address recruitment prior to study commencement as well as the need to have clear outreach strategies to optimize inclusion of marginalized groups. Recommendations and a guide are provided to inform the development of recruitment approaches of early career researchers in health and social science research.

Engaging Diverse Older Adults With Cognitive Impairment and Caregivers in Advance Care Planning: A Pilot Study of the Interactive PREPARE Website

INTRODUCTION

Engaging patients with cognitive impairment in advance care planning (ACP), including completing advance directives and naming health care proxies, before they lose decision-making capacity is important.

METHODS

We determined the feasibility of the PREPAREforYourCare.org ACP program among 20 diverse older adults with mild-to-moderate cognitive impairment and their caregivers in a 1-week, pre-post pilot. We examined ease-of-use, satisfaction, and feasibility using validated scales, and change in ACP Engagement scores, including knowledge, contemplation, self-efficacy, and readiness subscales (5-point scales), from baseline to 1-week.

RESULTS

Participants were on average 70 years old (SD=9.0), 45% Spanish-speaking, 60% had limited health literacy, and 15% felt comfortable using the internet. Patients and caregivers rated PREPARE a mean of 8.6 (SD=1.6) and 9.4 (SD=1.1) on the 10-point ease-of-use scale, 4.7 (SD=0.4) and 4.7 (SD=0.3) on the 5-point satisfaction scale, and 4.9 (SD=0.4) and 4.8 (SD=0.6) on the 5-point feasibility scale, respectively. ACP engagement scores increased for 16 of 20 (80%) patients (P=0.03) and 16 of 20 (80%) caregivers (P=0.18). Caregivers experienced increased knowledge (3.8 to 4.7, P=0.002) and self-efficacy (3.6 to 4.5, P=0.034) for ACP.

DISCUSSION

The PREPARE website was feasible and may facilitate ACP engagement among diverse older adults with cognitive impairment and their caregivers.

Recruiting and Retaining Dyads of Hospitalized Persons with Dementia and Family Caregivers

Persons with dementia have high rates of hospitalization, and along with their caregivers commonly experience negative hospital outcomes. The recruitment and retention of acutely ill older adults with dementia and caregivers can pose a challenge to investigators and threaten the validity of findings. The challenges encountered in an ongoing cluster randomized clinical trial in dyads of hospitalized persons with dementia and family care partners are described. The trial tests the efficacy of a nurse-family partnership model that aims to improve the following: (a) the physical and cognitive recovery in hospitalized persons with dementia, and (b) caregiver preparedness and anxiety. Strategies that address challenges include careful preplanning and preparation with the hospital site, strong communication with dyads and between team members, and honoring preferences and needs related to communication.

Designing and Implementing an IT Architecture for a Digital Multicenter Dementia Registry: digiDEM Bayern

Background  Registries are an essential research tool to investigate the long-term course of diseases and their impact on the affected. The project digiDEM Bayern will set up a prospective dementia registry to collect long-term data of people with dementia and their caregivers in Bavaria (Germany) supported by more than 300 research partners.

Objective  The objective of this article is to outline an information technology (IT) architecture for the integration of a registry and comprehensive participant management in a dementia study. Measures to ensure high data quality, study governance, along with data privacy, and security are to be included in the architecture.

Methods  The architecture was developed based on an iterative, stakeholder-oriented process. The development was inspired by the Twin Peaks Model that focuses on the codevelopment of requirements and architecture. We gradually moved from a general to a detailed understanding of both the requirements and design through a series of iterations. The experience learned from the pilot phase was integrated into a further iterative process of continuous improvement of the architecture.

Results  The infrastructure provides a standardized workflow to support the electronic data collection and trace each participant's study process. Therefore, the implementation consists of three systems: (1) electronic data capture system for Web-based or offline app-based data collection; (2) participant management system for the administration of the identity data of participants and research partners as well as of the overall study governance process; and (3) videoconferencing software for conducting interviews online. First experiences in the pilot phase have proven the feasibility of the framework.

Conclusion  This article outlines an IT architecture to integrate a registry and participant management in a dementia research project. The framework was discussed and developed with the involvement of numerous stakeholders. Due to its adaptability of used software systems, a transfer to other projects should be easily possible.

Strategies to engage people with dementia and their informal caregivers in dyadic intervention: A scoping review

Dyadic interventions simultaneously engage both people with dementia (PWD) and their informal caregivers (ICGs). This scoping review study identified the strategies for engaging dyads, described the perceptions of the dyads on these strategies, and reported the attrition rates of the dyadic interventions reported in the literature. Articles published up to July 2020, reporting a PWD-ICG-dyads intervention were searched in PubMed (Medline), PsycInfo, CINAHL, and the SSCI. Backwards citation chasing was conducted. A total of 37 studies were included. Seven engagement strategies were identified, which involved: ensuring a good-quality interventionist; offering take-home supporting materials; establishing peer support among the participants; tailoring the intervention content; conducting the intervention in a convenient location; conducting the intervention in a comfortable physical environment, and using a short and succinct programme. The dyads' subjective experiences of these strategies were reported. The attrition rates of the included studies were ranged 0% - 59.1%.

Negotiating Tensions between Methodology and Procedural Ethics

In this commentary, I consider what can go wrong in research when tensions arise between methodology and procedural ethics. I recount difficulties negotiating and implementing a participant recruitment strategy during my doctoral research project, which aimed to explore the experiences of people affected by dementia in the United Kingdom who were disengaged from services. To access this hard-to-reach population, I intended to adopt an informal recruitment strategy, snowball sampling from personal contacts and striking up conversations in public places. The procedural ethics committee were unhappy with this approach, deeming it potentially coercive. They suggested a more formal recruitment strategy enacted via emailing community organisations and churches. This approach entailed practical consequences that ultimately weakened the study sample, data and findings. This case raises questions about the negotiation of tensions between methodology and procedural ethics in gerontological research.

A tripartite model for recruiting African-Americans into fatherhood intervention research

Many studies have examined factors influencing African-American (AA) participation in research studies. But none inform the recruitment of AA men into fatherhood intervention research. Our purpose is to describe the recruitment and enrollment framework of the Dedicated African American Dad (DAAD) Study, a randomized controlled trial (RCT) designed to test a fatherhood intervention against a financial literacy comparison condition. AA nonresident (AANR) fathers are fathers who do not reside with their child on a full-time basis. Fathers attended 10 group-based sessions; and father and mother informants completed research interviews at baseline, postintervention, and 12 weeks postintervention. The DAAD Study tripartite model is a system of strategies that address three factors that individually and cooperatively affect recruitment of AANR fathers into research: community partnerships; study infrastructure; and recruitment personnel. The intersection of these three components forms a recruitment nexus that can be used to guide community-based research. The DAAD study serves as an exemplar of recruitment challenges, strategies, and lessons learned.

Recruitment of Individuals With Dementia and Their Carers for Social Research: Lessons Learned From Nine Studies

Many health and social care research studies report difficulties recruiting sufficient numbers of participants, adding to time and money expenditures and potentially jeopardizing the generalizability of findings. The current article reports the effectiveness and resource requirements of recruitment strategies used in nine dementia-related studies conducted in Australia. Articles, notices, or advertisements in targeted specialist newsletters were the most cost-effective method of recruitment. The use of service providers to aid recruitment yielded mixed results, but was lengthy in terms of research time. Online and social media were low cost but not reliably effective in terms of recruitment potential. Despite using multiple strategies to maximize recruitment, significant challenges were encountered achieving the required sample sizes; in most cases these challenges resulted in delays in the recruitment phase. Implications for researchers in the fields of dementia and general social/health research are discussed. [Res Gerontol Nurs. 2018; 11(3):119-128.].
